Description
Technical field
The present invention relates to mechanical fixture technology field, particularly relate to Height Adjustable scroll chuck.
Background technology
Scroll chuck utilizes to be distributed on moving radially of three movable jaws on chuck body, the machine tool accessories of Workpiece clamping and location; There is following point in current scroll chuck: 1) needs clamping manually, and automaticity is not high, and easily clamping is too tight or too loose; 2) during the cylindrical work that its clamped height is higher on vertical knee-type milling machine, due to three-jaw chuck pawl limited height, easily cause cylindrical work run-off the straight in process, cause mismachining tolerance.
Summary of the invention
The object of this invention is to provide automaticity high, and the Height Adjustable scroll chuck to highly higher cylindrical work firm grip.
Technical scheme of the present invention is as follows:
Height Adjustable scroll chuck, comprises discoid base; Described base is evenly equipped with three flutings, fluting medial surface is equipped with the first screw, is all provided with clamping device in this first screw; Described clamping device comprises screw rod, and screw rod is provided with moveable Mobile base, and the claw that Mobile base connects; Described screw rod one end extends outside the base and is connected with motor; Described claw is evenly equipped with some first tooth bars on the end face of one end, base center; Described claw end face is provided with pillar, and this pillar is arranged with moveable fixture block; Described fixture block is evenly equipped with some second tooth bars on the end face of one end, base center, and described fixture block side wall surface is provided with lock-screw.
Described fluting both sides are relatively set with two slide rails; Described Mobile base both sides are provided with two chutes relatively; Described slide rail and chute with the use of.
Described base center is provided with the second screw, is provided with backstay in this second screw; Be provided with bottom described backstay with the second screw with the use of threaded portion; Backstay outer surface above described threaded portion is evenly equipped with some spring leafs.
Described slide rail is in " convex " font; Described chute is in " convex " font.
The invention has the beneficial effects as follows: drive the rotation of screw rod by the startup of motor and then drive the movement of Mobile base, the mobile claw be connected with Mobile base that drives of Mobile base moves forward and backward; When claw move to prop up cylindrical workpiece time, disable motor, makes three claws be clamped by cylindrical work; Because claw is provided with the first tooth bar towards the one end at base center, adopt the first tooth bar to increase frictional force between claw and cylindrical workpiece, effectively can clamp cylindrical work; During due to the cylindrical workpiece longer at clamping axial length, claw is lower, easily clamp not strongly, crank, causing cannot clamp cylinders workpiece, by arranging fixture block and coordinating pillar, thus when clamping the longer cylindrical workpiece of axial length, effectively can avoid the problem of crank, and claw can make cylindrical workpiece firm grip with coordinating of fixture block.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is structural representation of the present invention;
Fig. 2 is partial structurtes schematic diagram of the present invention;
Fig. 3 is positional lever structure schematic diagram of the present invention;
In accompanying drawing, 1 is base, and 2 is fluting, and 3 is screw rod, and 4 is Mobile base.5 is claw, and 6 is motor, and 7 is the first tooth bar, and 8 is pillar, and 9 is fixture block, and 10 is the second tooth bar, and 11 is lock-screw, and 12 is slide rail, and 13 is chute, and 14 is guide rod, and 15 is backstay, and 16 is threaded portion, and 17 is spring leaf.
Detailed description of the invention
Embodiment 1
Shown in Fig. 1-Fig. 3, Height Adjustable scroll chuck, comprises discoid base 1; Described base is evenly equipped with three flutings 2, fluting medial surface is equipped with the first screw, is all provided with clamping device in this first screw; Described clamping device comprises screw rod 3, and screw rod is provided with moveable Mobile base 4, and the claw 5 that Mobile base connects; Described screw rod one end extends outside the base and is connected with motor 6; Described claw is evenly equipped with some first tooth bars 7 on the end face of one end, base center; Described claw end face is provided with pillar 8, this pillar is arranged with moveable fixture block 9; Described fixture block is evenly equipped with some second tooth bars 10 on the end face of one end, base center, and described fixture block side wall surface is provided with lock-screw 11.
Drive the rotation of screw rod by the startup of motor and then drive the movement of Mobile base, the mobile claw be connected with Mobile base that drives of Mobile base moves forward and backward; When claw move to prop up cylindrical workpiece time, disable motor, makes three claws be clamped by cylindrical work; Because claw is provided with the first tooth bar towards the one end at base center, adopt the first tooth bar to increase frictional force between claw and cylindrical workpiece, effectively can clamp cylindrical work; During due to the cylindrical workpiece longer at clamping axial length, claw is lower, easily clamp not strongly, crank, causing cannot clamp cylinders workpiece, by arranging fixture block and coordinating pillar, thus when clamping the longer cylindrical workpiece of axial length, effectively can avoid the problem of crank, and claw can make cylindrical workpiece firm grip with coordinating of fixture block.
Embodiment 2
Described fluting both sides are relatively set with two slide rails 12; Described Mobile base both sides are provided with two chutes 13 relatively; Described slide rail and chute with the use of.By slide rail and chute with the use of, avoid the rotation of Mobile base in moving process.
Embodiment 3
Described claw be connected two guide rods 14 between fixture block, this two guide rod is oppositely arranged on pillar both sides.By arranging guide rod, on the one hand opening guide effect, avoiding the radial rotating of fixture block on the other hand, cause the position of slotting with " V " shape not corresponding, affect clamping effect.
